<p>Win32::Process - Create and manipulate processes.</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>    use Win32::Process;
    use Win32;

    my $ProcessObj;

    sub ErrorReport{
        print Win32::FormatMessage( Win32::GetLastError() );
    }

    Win32::Process::Create($ProcessObj,
                                &quot;C:\\winnt\\system32\\notepad.exe&quot;,
                                &quot;notepad temp.txt&quot;,
                                0,
                                NORMAL_PRIORITY_CLASS,
                                &quot;.&quot;)|| die ErrorReport();

    $ProcessObj-&gt;Suspend();
    $ProcessObj-&gt;Resume();
    $ProcessObj-&gt;Wait(INFINITE);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>This module provides access to the process control functions in the Win32 API.</p>

<h1 id="METHODS">METHODS</h1>

<dl>

<dt id="Win32::Process::Create($obj,$appname,$cmdline,$iflags,$cflags,$curdir)"><a id="Win32"></a><a id="Win32::Process::Create-obj-appname-cmdline-iflags-cflags-curdir"></a>Win32::Process::Create($obj,$appname,$cmdline,$iflags,$cflags,$curdir)</dt>
<dd>

<p>Creates a new process.</p>

<pre><code>    Args:

        $obj            container for process object
        $appname        full path name of executable module (can be &#39;undef&#39;)
        $cmdline        command line args (can be &#39;undef&#39;)
        $iflags         flag: inherit calling processes handles or not
        $cflags         flags for creation (see exported vars below)
        $curdir         working dir of new process</code></pre>

<p>Returns non-zero on success, 0 on failure.</p>

<p>$appname can be &#39;undef&#39; to allow $cmdline to specify the command without an absolute path; $ENV{PATH} will be searched to find the executable. eg:</p>

<pre><code>    Win32::Process::Create($ProcessObj,
                           undef,
                          &quot;netstat -an&quot;,      # finds &quot;netstat.exe&quot; from $ENV{PATH}
                          0,
                          NORMAL_PRIORITY_CLASS,
                          &quot;.&quot;);</code></pre>

<p>See Microsoft&#39;s CreateProcess() docs for details. For instance, only .exe&#39;s will be searched; if you are trying to run a .com or .bat, you&#39;ll have to specify the extension, eg:</p>

<pre><code>    Win32::Process::Create($ProcessObj,
                           undef,
                          &quot;tree.com /A /F&quot;,
                          [..]</code></pre>

</dd>
<dt id="Win32::Process::Open($obj,$pid,$iflags)"><a id="Win321"></a><a id="Win32::Process::Open-obj-pid-iflags"></a>Win32::Process::Open($obj,$pid,$iflags)</dt>
<dd>

<p>Creates a handle Perl can use to an existing process as identified by $pid. The $iflags is the inherit flag that is passed to OpenProcess. Currently Win32::Process objects created using Win32::Process::Open cannot Suspend or Resume the process. All other calls should work.</p>

<p>Win32::Process::Open returns non-zero on success, 0 on failure.</p>

</dd>
<dt id="Win32::Process::KillProcess($pid,-$exitcode)"><a id="Win322"></a><a id="Win32::Process::KillProcess-pid---exitcode"></a>Win32::Process::KillProcess($pid, $exitcode)</dt>
<dd>

<p>Terminates any process identified by $pid. $exitcode will be set to the exit code of the process.</p>

</dd>
<dt id="$ProcessObj-&gt;Suspend()"><a id="ProcessObj--Suspend"></a>$ProcessObj-&gt;Suspend()</dt>
<dd>

<p>Suspend the process associated with the $ProcessObj.</p>

</dd>
<dt id="$ProcessObj-&gt;Resume()"><a id="ProcessObj--Resume"></a>$ProcessObj-&gt;Resume()</dt>
<dd>

<p>Resume a suspended process.</p>

</dd>
<dt id="$ProcessObj-&gt;Kill($exitcode)"><a id="ProcessObj--Kill-exitcode"></a>$ProcessObj-&gt;Kill($exitcode)</dt>
<dd>

<p>Kill the associated process, have it terminate with exit code $ExitCode.</p>

</dd>
<dt id="$ProcessObj-&gt;GetPriorityClass($class)"><a id="ProcessObj--GetPriorityClass-class"></a>$ProcessObj-&gt;GetPriorityClass($class)</dt>
<dd>

<p>Get the priority class of the process.</p>

</dd>
<dt id="$ProcessObj-&gt;SetPriorityClass($class)"><a id="ProcessObj--SetPriorityClass-class"></a>$ProcessObj-&gt;SetPriorityClass($class)</dt>
<dd>

<p>Set the priority class of the process (see exported values below for options). Note that the ABOVE_NORMAL_PRIORITY_CLASS and BELOW_NORMAL_PRIORITY_CLASS classes only work on Windows 2000 and later.</p>

</dd>
<dt id="$ProcessObj-&gt;GetProcessAffinityMask($processAffinityMask,-$systemAffinityMask)"><a id="ProcessObj--GetProcessAffinityMask-processAffinityMask---systemAffinityMask"></a>$ProcessObj-&gt;GetProcessAffinityMask($processAffinityMask, $systemAffinityMask)</dt>
<dd>

<p>Get the process affinity mask. This is a bitvector in which each bit represents the processors that a process is allowed to run on.</p>

</dd>
<dt id="$ProcessObj-&gt;SetProcessAffinityMask($processAffinityMask)"><a id="ProcessObj--SetProcessAffinityMask-processAffinityMask"></a>$ProcessObj-&gt;SetProcessAffinityMask($processAffinityMask)</dt>
<dd>

<p>Set the process affinity mask. Only available on Windows NT.</p>

</dd>
<dt id="$ProcessObj-&gt;GetExitCode($exitcode)"><a id="ProcessObj--GetExitCode-exitcode"></a>$ProcessObj-&gt;GetExitCode($exitcode)</dt>
<dd>

<p>Retrieve the exitcode of the process. Will return STILL_ACTIVE if the process is still running. The STILL_ACTIVE constant is only exported by explicit request.</p>

</dd>
<dt id="$ProcessObj-&gt;Wait($timeout)"><a id="ProcessObj--Wait-timeout"></a>$ProcessObj-&gt;Wait($timeout)</dt>
<dd>

<p>Wait for the process to die. $timeout should be specified in milliseconds. To wait forever, specify the constant <code>INFINITE</code>.</p>

<p>Returns a false value if the process is still alive by the time timeout expires:</p>

<pre><code>    if ( $process-&gt;Wait(1) ) {
        print &quot;Process is done\n&quot;;
    }
    else {
        print &quot;Process is still running\n&quot;;
    }</code></pre>

</dd>
<dt id="$ProcessObj-&gt;GetProcessID()"><a id="ProcessObj--GetProcessID"></a>$ProcessObj-&gt;GetProcessID()</dt>
<dd>

<p>Returns the Process ID.</p>

</dd>
<dt id="Win32::Process::GetCurrentProcessID()"><a id="Win323"></a><a id="Win32::Process::GetCurrentProcessID"></a>Win32::Process::GetCurrentProcessID()</dt>
<dd>

<p>Returns the current process ID, which is the same as $$. But not on cygwin, where $$ is the cygwin-internal PID and not the windows PID. On cygwin GetCurrentProcessID() returns the windows PID as needed for all the Win32::Process functions.</p>

</dd>
</dl>
